Great news, SV!
So you know that if the aircraft yaws of its own accord, without the rudder pedals moving, you'll do one drill, and if the pedals move without your input, you'll do the other.
Also, remember that the 'engine fire' drill is not an engine fire drill, but an 'engine fire, severe damage, or separation' drill. If the engine falls off the wing, what's the point in firing the bottle?
Maybe most important is to ask, how many of your colleagues are still unaware, and what are your trainers and checkers doing about it?
I think that we agree that the Boeing manuals are, in every respect, of the lowest quality, but they are all we have got, so it's important to get to grips with them......
I don't for one moment suppose anyone from Boeing would care to come in on this thread for a proper analysis of the 737 paperwork...?
